Australia is being "swamped by Asians", mosques need to have security cameras, halal-certified food is funding terrorism and "Communist China" shouldn't own Australia's electricity.These are the words of the woman who is now one of Australia's most powerful politicians, newly-elected senator Pauline Hanson.Hanson was confirmed elected to the Australian Senate last week, along with three other members of her One Nation party, according to the Australian Electoral Commission.

I've been to Australia and I always thought that the number of Asians are at a sustainable level. Has something changed?
